They can wander to the bottom of the sea, swim or live in very humid environments that allow them to breathe.
Despite these limitations, the study's basic findings are likely generally applicable. Horseshoe crabs have been called “living fossils” because they predate the dinosaurs by more than 200 million years.

Dr. Martin Doerfler, senior vice president of clinical strategy and development at Northwell Health, was one of the thousands of health care professionals who witnessed the transition.
"We went from the proverbial 'zero to 60' over a matter of weeks, and provided good care with very high degrees of patient satisfaction," Doerfler said.
Prior to the pandemic, Northwell Health—the largest hospital system in New York—was conducting about 150 telehealth visits per month between 20 to 40 physicians.

In a 2010 YouTube interview with members of the physics and astronomy faculty at the University of Nottingham, several academic experts admitted that they had little idea what would happen if one were to stick a hand inside the proton beam at the LHC.

Land crabs have a sort of lung, made from a modified gill chamber. This assault on a cell's genetic programming can kill the cell, stop it from dividing, or induce a cancerous mutation.
